Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish and set aside.
Season chicken breasts with salt and black pepper. Heat olive oil in a skillet over medium-high heat, and sear the chicken on both sides until golden brown, about 3-4 minutes per side (the chicken does not need to be fully cooked). Remove chicken and set aside.
In the same skillet, add the chopped onion and sauté for 2-3 minutes until softened. Add the minced garlic and cook for 1 minute until fragrant. Stir in the sliced mushrooms and cook for an additional 5 minutes until softened. Remove from heat.
In a large mixing bowl, combine cream of chicken soup, sour cream, milk, and 1 cup of the shredded cheddar cheese. Mix well to form a creamy sauce.
Fold the frozen mixed vegetables into the creamy sauce, followed by the sautéed onion, garlic, and mushrooms. Mix until evenly combined.
Spread half of the creamy vegetable mixture into the prepared baking dish. Lay the seared chicken breasts on top, and then spread the remaining creamy vegetable mixture over the chicken.
Sprinkle the remaining 1 cup of shredded cheddar cheese evenly over the top.
In a small bowl, combine the bread crumbs and melted butter. Sprinkle the breadcrumb mixture evenly over the casserole for a crispy topping.
Bake in the preheated oven for 35-40 minutes, or until the casserole is bubbling and the topping is golden brown.
Remove from the oven and let rest for 5-10 minutes before serving. Enjoy your hearty chicken casserole!
